Sensor Learning Course
Learning Module 23: Limit Switches, Proximity Sensors and Photoelectric Sensors
Proximity Sensor Types
Proximity sensors come in a wide variety of designs to meet the requirements of almost any
industrial application. Let’s take a brief look at the types that are available.
Proximity Sensors
Type Application
Modular limit switch type The modular design can be tailored for many application types. Components can
be easily switched out for short-run manufacturing changes.
Unitized limit switch type The sealed body protects the components in corrosive environments.
Tubular This is the design of choice for a growing number of applications. The small size
allows for easy mounting in a fixture or for use in tight spaces found on many
assembly lines.
Right angle tubular This style enables mounting in tight locations.
High current tubular Enables the smaller tubular design to carry extremely large inrush and continuous
currents. Excellent for heavy equipment such as lift trucks.
Composite housing This corrosion-resistant unit performs well in high wash-down areas such as food
processing, or places where caustic chemicals abound.
Pancake The extra wide coil on this unit achieves the widest and farthest range available:
3.94 in. Ideal for oil rig applications and assembly of large parts.
